摘要
小型水体(如湖泊、河流、水塘等)的沉积物中存在高浓度重金属物质,如铅(Pb)、镉(Cd)、汞(Hg)、铬(Cr)等,受水体流动情况、沉积速度等因素影响,使得重金属具有复杂的迁移转化过程,难以准确监测扩散情况。为此,研究一种重金属污染扩散动态监测方法。采样测定各小微水体底泥中的重金属含量,建立多水质Agent三角形网格系统,根据内梅罗污染指数判断对应底泥发生污染扩散时的重金属浓度,得到正在发生污染扩散的区域,完成重金属污染扩散的动态监测。分析监测结果,所提方法的采样测定精度与污染扩散的监测精度均较高。
The sediments of small water bodies(such as lakes,rivers,ponds,etc.)contain high concentrations of heavy metals,such as lead(Pb),cadmium(Cd),mercury(Hg),chromium(Cr),etc.Affected by water flow and deposition rate,heavy metals have a complex migration and transformation process,and it is difficult to accurately monitor their diffusion.Therefore,a dynamic monitoring method of heavy metal pollution diffusion was studied.The heavy metal content in the sediment of each small and micro water body was measured by sampling.The multi-water quality Agent triangular grid system was established to determine the heavy metal concentration at the time of pollution diffusion in the corresponding sediment according to the Nemero pollution index,.The area where pollution diffusion was occurring was obtained to complete the dynamic monitoring of heavy metal pollution diffusion.Analysis of the monitoring results shows that the sampling accuracy of the proposed method and the monitoring accuracy of pollution diffusion are both high.
